The Ridged Fractal node produces a fractal pattern in grayscale format. This generates a memory-efficient texture with ridged waves and fractal patterns (Figure 1).

Power
Controls the texture's overall brightness.
Ridge Height
Controls the fractal pattern values. Lower values yield a darker pattern, and higher values produce a lighter pattern.
Octaves
Controls the amount of detail in the texture.
Omega
Controls the details in the underlying fractal pattern.
Lacunarity
Controls the size of the gaps in the fractal pattern.
Transform
Accepts the input of a Transform node.
Projection
Accepts a Projection node, which determines how the noise maps to the surface. If left blank, the object's UV texture coordinates determine the mapping.
